Abstract
The invention discloses a mixed herbicide containing picloram and metamifop, and belongs to the technical field of pesticides. The herbicide is prepared from picloram and metamifop in a mass ratio of (0.1-80): (0.1-80) as main effective ingredients. The mixed herbicide has the advantages of quick response, wide herbicide controlling spectrum, long duration, complete weed control, low residue, low toxicity, safety, environmental friendliness and the like when applied to weeding of bare places, orchards, forest lands, paddy fields and wheat paddocks, and is a high-quality chemical herbicide for bare places, orchards, forest lands, paddy fields and wheat paddocks.
Description
Technical field
The invention belongs to technical field of pesticide, especially weed killer herbicide field, relate to the binary built agent of the acid of chlorine Fampridine and metamifop.This herbicidal composition can be applicable to uncultivated area, orchard, forest land, paddy field and wheat paddock postemergence weed control.
Background technology
Chlorine Fampridine acid (aminopyralid), amino-3, the 6-dichloropyridine-2-carboxylic acids of chemical name: 4-, the acid of chlorine Fampridine is a kind of pyridines weed killer herbicide, is widely used in the control of weeds of mountain region, grassland, lawn, plantation and uncultivated area.Annual or perennial broadleaf weed can be prevented and treated.
Metamifop (metamifop), chemical name: (R)-2-{ (4-chloro-1,3-benzoxazoles-2-base oxygen) phenoxy group }-2'-fluoro-N-methyl-prop anilid, belong to aryloxyphenoxypropanoates class weed killer herbicide, be acetyl-CoA carboxylase (ACCase) inhibitor, the synthesis of vegetable fatty acid can be suppressed.After medication, in several days, sensitive varieties occurs that blade face is moved back green, Developing restraint.Can be fabulous prevent and kill off most of annual gramineous weed, with great majority this type of weed killer herbicide unlike, metamifop, to rice safety, can effectively prevent and kill off paddy field main weeds, as barnyard grass, moleplant seed, lady's-grass and eleusine indica, be mainly used in transplanting and direct sowing rice field weeding.Low toxicity, environmentally safe, having miscibilty widely, and be expected to for other crops and Kill weeds, is a very promising weed killer herbicide.
Current chlorine Fampridine acid residue problem is serious, has been strictly limited usage amount and using method in a lot of countries and regions.In order to while minimizing herbicide carryover, guarantee the herbicidal effect of medicament, be made into mixture after selecting the acid of chlorine Fampridine and metamifop two kinds of suitable decrements of weed killer herbicide to use, so both expand herbicide spectrum, significantly improve herbicidal effect, it also avoid possibility succession crop being produced to residual hazard.
Summary of the invention
The object of this invention is to provide the mixed herbicide of a kind of chloride Fampridine acid and metamifop.
Another object of the present invention is to provide the application of this weed killer herbicide in uncultivated area, orchard, forest land, paddy field and wheat paddock weeding.
The mixed herbicide of a kind of chloride Fampridine acid and metamifop, it is characterized in that this weed killer herbicide with chlorine Fampridine acid with metamifop for principle active component, the acid of chlorine Fampridine is 0.1 ~ 80:0.1 ~ 80 with the mass ratio of metamifop, preferred chlorine Fampridine acid is 1 ~ 60:1 ~ 60 with the mass ratio of metamifop, and most preferably the acid of chlorine Fampridine is 1:0.5 ~ 2 with the mass ratio of metamifop.
In mixed herbicide, the acid of chlorine Fampridine is 1 ~ 85% with the mass percentage of both metamifops in weed killer herbicide, and preferred mass percentage composition is 10 ~ 75%.
Mixed herbicide of the present invention, wherein the acid of chlorine Fampridine exists with the form of water soluble salt, and the water soluble salt of described chlorine Fampridine acid comprises the water soluble salts such as sodium salt, sylvite, ammonium salt, isopropyl amine salt, methylamine salt, dimethylamine salt, alcohol salt, triethanolamine salt, triisopropanolamine salt.
Chlorine Fampridine acid of the present invention is with the binary built preparation of metamifop, except the acid of chlorine Fampridine is with except metamifop active ingredient, the auxiliary agents such as conventional surfactants, thickener, solvent or the solid packing that pesticidal preparations allows can also be added and be mixed with any one formulation that agricultural chemicals allows.Preferably be processed into missible oil, suspending agent, aqueous emulsion, microemulsion, soluble liquid, wetting powder, water dispersible granules.
" % " of the present invention is mass percentage.
The application of mixed herbicide in uncultivated area, orchard, forest land, paddy field and wheat paddock weeding of chloride Fampridine acid of the present invention and metamifop, has remarkable result preventing and kill off the application in uncultivated area, orchard, forest land, paddy field and wheat paddock in various broad leaved weed.
Compared to the prior art, beneficial effect of the present invention:
Mixed herbicide of the present invention, has instant effect, herbicide spectrum width, and the advantages such as the lasting period is long, weeding is thorough, it is low to remain, low toxicity, safety and environmental protection are the uncultivated area of high-quality, orchard, forest land, paddy field and wheat paddock chemical herbicide.
